Here is what I get when I deploy my webapp with a very basic web.xml
containing only one HelloWorldServelt, no filters and no listeners.
I still get a 9-10 seconds deploying time :
03-06 12:54AM 35.471 /helloworld 200 9558ms 3966cpu_ms 0kb Mozilla/5.0
(Windows; U; Windows NT 6.0; en-US) AppleWebKit/533.2 (KHTML, like Gecko)

So deploying time seems to be proportional to the global size of
code/librairies you deploy even if this code is never called.
For you information, here is my HelloWorldServlet service method :
public void service(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.getWriter().print("Hello World");
}
And here is my web.xml :
<web-app>
<servlet>
<servlet-name>HelloWorldServlet</servlet-name>
<servlet-class>com.mably.cms.web.HelloWorldServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>HelloWorldServlet</servlet-name>
<url-pattern>/helloworld</url-pattern>
</servlet-mapping>
<!-- Default page to serve -->
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
If anybody at Google have some hints about that, they're welcome.
My "simplified" testing app has ID "i-wands".
